-replace不会用"()"替换字符串

Question

我正在尝试在PowerShell中替换包含括号的字符串.但是,当我尝试这样做时,它无法正常工作.

知道我哪里出错了吗？什么是我该做的更换包含字符串()与-replace在PowerShell中？

$a='Some Text with (round) brackets. This text is long.'
$ch="with (round) brackets."
$b="this text"
$a -replace $ch,$b

输出:

Some Text with (round) brackets. This text is long.

Answer 1

-replace使用正则表达式,所以你必须逃避你的regex:

$a='Some Text with (round) brackets. This text is long.'
$ch="with (round) brackets."
$b="this text"
$a -replace [regex]::Escape($ch),$b

输出:

Some Text this text This text is long.
